\section{Standard Modules \sectcode{UserDict} and \sectcode{UserList}}
|
||
|
Each of these modules defines a class that acts as a wrapper around
|
||
|
either dictionary or list objects. They're useful base classes for
|
||
|
your own dictionary-like or list-like classes, which can inherit from
|
||
|
them and override existing methods or add new ones. In this way one
|
||
|
can add new behaviours to dictionaries or lists.
|
||
|
|
||
|
\renewcommand{\indexsubitem}{(in module UserDict)}
|
||
|
The \code{UserDict} module defines the \code{UserDict} class:
|
||
|
|
||
|
\begin{funcdesc}{UserDict}{}
|
||
|
Return a class instance that simulates a dictionary. The instance's
|
||
|
contents are kept in a regular dictionary, which is accessible via the
|
||
|
\code{data} attribute of \code{UserDict} instances.
|
||
|
\end{funcdesc}
|
||
|
|
||
|
\renewcommand{\indexsubitem}{(in module UserList)}
|
||
|
The \code{UserList} module defines the \code{UserList} class:
|
||
|
|
||
|
\begin{funcdesc}{UserList}{\optional{list}}
|
||
|
Return a class instance that simulates a list. The instance's
|
||
|
contents are kept in a regular list, which is accessible via the
|
||
|
\code{data} attribute of \code{UserList} instances. The instance's
|
||
|
contents are initially set to c copy of \var{list}, defaulting to the
|
||
|
empty list \code{[]}. \var{list} can be either a regular Python list,
|
||
|
or an instance of \code{UserList} (or a subclass).
|
||
|
\end{funcdesc}
